Wizkids Rules!

The Save Civilians BAC states: "Whenever you field a Sidekick this turn, reduce the fielding cost of another die by 1, draw a die from your bag, and put it in your Prep Area."

I know from the underdog ruling that characters are considered in the field for the timing of when fielded effects, so would Ally characters trigger this BAC effect?

Yes. Fielding character dice with the Ally keyword would trigger the ability of Save Civilians.
